HERA members can you help? An essential objective of the AGGAT program under this research aim is the installation of a materials test rig on a geothermal site to investigate field-based geothermal scaling and corrosion. The data gathered in turn will accumulate into an industry owned information database to base future decisions on in terms…
For structural steel products to be free from serious problems in production and in service, it is necessary to provide a suitable level of quality management from the design phase, through material selection, into fabrication, and subsequently inspection. Requirements for welding/fabrication activities are given in the Code of Practice of the NZ Steel Fabricator Certification…
HERA member EHL provided the basis for US energy innovator Northwest Energy Innovations’ wave energy device, which was successfully deployed at the US Navy Wave Energy Test Site (WETS) near Kaneohe Bay, Oahu, Hawaii. The device, called Azura, will be deployed for 12 months of grid-connected testing as part of a rigorous programme to commercialise…
There is an increasing dialogue out in the market place about non-standard products being sold into the building and construction industry in NZ. The alleged numbers being reported are significant and almost somewhat unbelievable. But if they are anywhere near reality, we do need to be taking some form of action otherwise ‘Standards creep’ will…
The recent tender round for a Christchurch cornerstone project highlighted the need for clarity around what information is required to allow the procurement decision makers to comply with the new Government Rules of Sourcing whose 3rd Edition came into force on the 1st July 2015. On 1st February 2015 an additional 103 crown entities joined the 29…
Yesterday our member New Zealand Steel celebrated their 50 year anniversary. Forming an integral part of this country’s history for half a century. The company was formed on 26 July, 1965; steel production began in 1968 and major expansions were completed in 1987, creating an integrated steel mill. Located in Glenbrook, South West of Auckland,…
Temperature-time (T-t) curves and temperature contour plots due to the ISO 834 standard fire loading curve for typical New Zealand composite floors have been calculated and presented in tabulated format. The temperatures in 10 minute intervals up to the requested fire resistance rating have been reported for the slab top face and along the thinnest…
In May 2015, Standards Australia senior management was alerted to the fact that the 2014 editions within the AS/NZS 1554 suite contained material that was included without adherence to Standards Australia’s standards development processes. The relevant material relates to specifications contained in the following standards: AS/NZS 1554.1:2014 Structural Steel Welding, Part 1: Welding of steel…
Representatives from the Geothermal New Zealand group met earlier this month in Auckland to follow up on outcomes from the World Geothermal Congress (WGC) held in Melbourne recently. Mike Allen (Executive Director Geothermal NZ) chaired the meeting of about 25 attendees to lead through a busy agenda of items which included international geothermal updates and…
As the new design standard for composite construction AS/NZS 2327 nears completion, consideration is being paid to what software tools will be needed by designers. Our General Manager Structural Systems Dr Stephen Hicks has encouraged Arup’s software house Oasys to implement the new AS/NZS 2327 within their Compos programme, which enables users to design composite beams…
We have an image problem. In experimental evolution, Drosophila (the humble fruit fly) is often used to demonstrate evolutionary processes. It is used because genetic changes for the fruit fly can be observed very quickly in response to natural selection. In business, the equivalent of the fruit fly is the IT or information technology company,…
Research Aim 1-1 – Expert Design Tool A major objective of the Above Ground Geothermal and Allied Technologies (AGGAT) Research Programme is to make the assessment of heat resources potential for energy generation (geothermal / waste heat) easier for heavy engineering member companies involved in the clean energy space. This objective is being addressed through…
